To all whom it may concern lie it known that l} l'nfcrors Fl. Bail-mar, a citizen of the linited ldtates. rcr-iiding at ll'est Palm licach. in the county of Palm Beach and State of Florida, have invented certain new and useful Improvements in Flashlights: and l do hereby declare the following to be a full, clear, and exact description of the invention. such as will on able others skilled in the art to which it appertains to make and usethe same.

This inventionielates to improvements in lash-lights, and hasitor one of its objects the provision of a device of this character having convei-iicnt means for opening and closing; the electric circuit to the electric lamp when desired.

Another object of this invention is the pro vision of a novel means For establishing an.

electrical connection between the battery;

electric lamp, and the circuit closing means, and which is entirel protected by the casing wlnlc in use.

i l further object of this invention is the vention, reference will be had to the following description and accompanying drawing, in which:

Figure 1 is a side elevation of a flash-light constructed in accordance with my invention,

Fig. 2 is a vertical sectional view of the same, and p Fig. 3 is an end View, illustrating the circuit closing: means, a

l ieterring in detail to the drawing, the numeral 1 indicates a cylindrical easing constructed from insulating: material and has each end open. A bottom closure cap 2, constructed of insulating material is secured to one end ofthe casing- 1 by means of set screw 3 and carries a contact 4-, which has one end disposed exteriorly thereof for engagement with a switch 5, while the opposite end engages the lower end ot? a battery 6. llhe ba ttcrr 6 is located within the casing 1, and is swinging the bar into engagement with the supported in spaced relation to the cap 2 by means o'l' an enlar 'ed portion h" constructmji of insulating" material carried by the cap and the contact l. The enlarged portion 6 is of hollow formation and has one end a contact 7 located therein, and which contact is carried by a closure cap a in spaced relation to the contact l. in insulated wire 53 is connected to the inner end of the contact 1 I. and extends out of the enlarged portion ('1 upwarill along the walloi the casing fl, and is connected to a contact Ill. 'arried by the upper end of the casing l. 'lhelast-named end of the casing: 1 has mounted thereon an externally threaded metallic collar 1' which engages the outer end oi the contact 10" ilc sleeve l2 has one end internally: threaded for coiipcration with the screw threads upon thecollar ll whcreb the sleeve is dctachably secured to the casing l. The sleeve l2 has tormcd therein a retractor 1th provided with an internally screw threaded socket ll tor receiving an electric lamp l5. lhe electric lamp 1? extends through the socket 171- i'for S0 engagement with the upper end of the hattery. as illustrated at 16. A lens-sup nn'ting member 17, carrying a lens 18, is secured to the outer end of the sleeve 12 for supporting the lens directh in front of the electric lamp and the reflector 13.

. The switch 5 consists of a bar that is picotallv connected to the contact. 'Z and has onnected to its free end a handle it) to):

contact -l. whereby an electric circuit, is completed to the electric lamp. A stop 20 is carried by the closure cap "2, and is adapted to limit the movement of the switch 53 in one directimi'or when disconnected from the con tact l, as clearly illustrated in l igr. 3.

llhen it is desired to remove or replace the battery -(3 in the casing l. the sleeve 12 is detached from the casing 1. whereby the battery can be readily withdrawn or replaced in the casing, as desired.

i rhile l have shown and described the preferred enilmdimentof my inventioin it will be understood that minor (ranges in corn struction, combinatimi and arrangement of parts may be made without (leparting from the spirit and scope oi the invention as claimed.

l'lavingrthus described my invention, What I claim is:

A. flash light including an insulated casing having each end open, a metallic sleeve do tachably secured to one end of the casing, a battery in said casing, a reflector formed in said sleeve and supporting an electric lamp in engagement With the battery, a. cap closing theothcr end of said casing, a contact secured to the cap and engaging the battery and projecting exteriorly of said cap, a hollow insulated offset portion formed on the cap and engaging the battery for aiding in supportin the battery, a second contact secured to tiie cap and prevented from engaging the *battery by said offset portion and extending exteriorly of the cap, means conment with the outer end of the first named contact.

In testimony whereof I :ifiix my signature 20 in presence of two witnesses. LUCIOU S r AND EH55 Witnesses C. J. Pn'rnnsnx, E. L. STEEN.
